Leftover melted finger.
An example of the element Yttrium

Leftover melted finger.
Description supplied by the source:
This is another sample of yttrium, except this one was melted from bulk hemispheres also shown on this site. This material was melted into a long finger-shaped mold in order for it to be machined (very carefully!) into a rod. The mold was much longer than this, but this piece did not end up being used, for whatever reason.Source:Ethan CurrensContributor:Ethan CurrensAcquired:30 April, 2008Text Updated:30 April, 2008Price: AnonymousSize: 1"Purity: 99.9%
